3M™ Scotch-Weld™ Epoxy Adhesive 2290
3M™ Scotch-Weld™ Epoxy Adhesive 2290 is an amber tinted thermosetting epoxy adhesive and coating. It is designed for metal to metal coating and subsequent bonding.
  • Offers exceptionally high shear and peel strength
  • One-part formula eliminates messy mixing processes, saving time and increasing efficiency
  • Dries to a tack-free film which allows bonds to be made up to 3 months later for B-staging and multi-stage processes
  • Excellent wetting during cure requires only coating a single surface
  • Requires only sufficient pressure to keep bonded parts dimensionally stable

Overview

Bond, Laminate, Protect
3M™ Scotch-Weld™ Epoxy Adhesive 2290 is designed to coat and bond metal substrates, including steel and aluminum. This epoxy is a low (21% solids) formulation with very low viscosity. 3M™ Scotch-Weld™ Epoxy Adhesive 2290 adhesive can be applied in a variety of methods including: brushing, flow coating, dip coating, roll coating, knife coating and spraying. it is ideal for assembling metal laminations and various applications on metal cores, rotors and motors and wire windings. B-staging coated and dried parts are optional; allowing final cure up to 3 months later.

Recommended Applications

  • Assemble laminated steel cores for electrical motor stators and rotors
  • Adhere copper foil to B-staged epoxy in the manufacture of printed circuits
  • Coat, protect and utilize coils and electronic subassemblies
  • Thin metal stack laminations such as those used in magnetic tape heads

 

One-part heat cured epoxies are rigid adhesives that have outstanding strength when measured at elevated temperatures. These adhesives require a thermal cure, typically around 250-350°F (120-180°C) for 40-60 minutes, to achieve full strength. They generally have the highest strength and overall performance. They also provide the best resistance to high temperatures, solvents and outdoor weathering. Epoxy adhesives usually require clean, abraded surfaces to obtain maximum bond strength.
